Powers/Abilities: Skilled fighter, trained in a variety of combat
styles. Excellent marksman. The "superhero" costume his bosses eventually
gave him was bullet proof and had "servo mechanisms" which enhanced his strength
to superhuman levels.

History:
John Targitt was an F.B.I. Special agent whose wife and daughter were killed
when the plane they were on was blown up by a bomb set to eliminate a mob
boss, Bert Manetti. Investigating the site where the remains of the plane
came to Earth, Targitt discovered clues which led him to Boston on the trail
of the killers. Once there he faced mob assassins before locating and eliminating
the killer of his family. His vigilante actions had drawn the mobs ire though,
and they sought to eliminate him, which in turn led to a gun battle between
mob hitmen and several F.B.I. men. In direct defiance of orders from Carl,
his boss, Targitt followed a lead he had discovered to destroy a major drugs
shipment arriving in the U.S. by sea; this earned him a price on his head
from the Mob.

Targitt intended to quit the Bureau after this, believing the Mob held him
higher regard than the F.B.I. did, but he was beaten to the punch when Carl
fired him before he could resign, because of the unwanted press his actions
have drawn. Needing to re-arm himself after handing in his service issue
weapon, Targitt went to visit his former partner Hunch, who now owned an
antiques gun shop. He was shocked to encounter Carl there, waiting for him.
Carl explained that his firing was faked to keep the F.B.I. chiefs happy,
but that Carl now wanted him to work undercover as a covert agent.

Armed with a high-tech costume which made him bulletproof, Targitt's first
new mission was to locate and stop the people behind attacks on the Alaskan
Oil Pipelines. This led to his first encounter with the criminal known as
Professor Death.

Paul Muir notes that "As part of the Atlas re-design of their characters
(i.e. they were going to the wall and everyone became a superhero to try
to save the line) Targitt became "John Targitt ManStalker" with issue 3 (last
issue) - the costume was given to him by his bosses to help him fight that
issue's villain Professor Death.

Prof
Death was Prof Hannibal Burns, born in Munich and adopted by US Army Colonel.
He was working on a nerve gas (Dethx-13) when he made a mistake and there
was an explosion with the gas whish turned him into Professor Death."
Thanks to Paul also for providing an image of John in his full (i.e. helmeted)
costume, and telling me about the costume's capabilities. Grant Forsythe
states that he apparently got his costume slightly earlier than Paul says,
back in issue #2 of his title.
